To configure expect_test, add the following at the top of your .ml file, or in some import.ml:
module Expect_test_config = struct include Expect_test_config let pre_redirect_hook () = ... end

module Upon_unreleasable_issue : sig ... end
module type S = sig ... end
module IO : sig ... end
val flush : unit -> unit IO.t
Flush whatever need to be to get pending output out on file descriptor 0.
val run : ( unit -> unit IO.t ) -> unit
Run an IO operation until completion
Synchronous check that there is no pending output on file description 0. With async, there is no guarantee that on the rhs of a

val upon_unreleasable_issue : Upon_unreleasable_issue.t
upon_unreleasable_issue specifies how to deal with output that should not be released even if it is accepted (e.g. backtraces). The default is
